完形填空 (共20小題;每小題1.5分,滿分30分)

A beggar, carrying a shabby(破舊的) old wallet, was begging alone from house to house. As he complained about his 36 , he kept wondering that people who lived in 37 houses should always be unsatisfied, 38 rich they might be, and they should go so far as to 39 all they have.

       “Here, for example,” he said, the former master of this house succeeded in trading, and made himself very rich. By then, instead of stopping, and handing over his 40 to another, and spending the rest of his years 41 peace, he took to(從事) equipping ships. He expected to get mountains of gold; but the ships were 42 , and his treasures were lost. Now they all lie at the bottom of the sea, and he has found his 43 disappeared like those in dreams. In short, examples of this are 44.

       At this moment Fortune suddenly appeared to the beggar and said, “Listen! I have long wished to 45 you. Here are a lot of gold coins I have found. Hold out your wallet, and I will fill it with them; but only on this condition: All shall be gold that falls into the wallet, but if 46 of them falls out of the wallet to the ground, it 47 become dust. Consider this well. I have warned you I shall 48 keep my word. Your wallet is old, don’t fill it 49 its power.” The beggar was almost too overjoyed to breathe. He 50 felt the ground below his feet. A stream of coins were poured 51 it. The wallet soon became rather heavy.

       “Is that 52 ?” “Not yet,” “Isn’t it 53 ?” “Never fear.” “Consider, you are a millionaire.” “Just a little more, just 54 a handful,” But at that moment the wallet broke, the gold coins 55 dust and Fortune disappeared. The beggar had nothing but his empty wallet and remained as poor as before.

“The pen is more powerful than the sword(刀).” There have been many writers who used their pens to fight things that were wrong. Mrs Harriet Beecher Stowe was one of them.

  She was born in the U.S.A. in 1811.One of her books not only made her famous but has been described as one that excited the world, and was helpful in causing a civil war and freeing the enslaved race. The civil war was the American Civil War of 1861, in which the Northern States fought the Southern States and finally won.

  This book that shook the world was called Uncle Tom's Cabin. There was time when every English-speaking man, woman, and child has read this novel that did so much to stop slavery.  Not many people read it today, but it is still very interesting. The book has shown us how a warm-hearted writer can arouse (喚起) people's sympathies. The author herself had neither been to the Southern States nor been a slave. The Southern Americans were very angry at the book, which they said did not at all represent true state of affairs, but the Northern Americans were wildly excited over it and were so inspired by it that they were ready to go to war to set the slaves free.

Directions: Read the passage carefully and answer the questions or complete the statements in the fewest possible words.

    We’d like to agree with the recent report comparing the difference between a TV and a computer: When you use one you turn your brain on, with the other you turn it off.

Your brain may not be the only thing the TV turns off. It seems that men who watch a lot of TV are more sedentary, eat more food and are generally much fatter. Similar result have been found for women. Experts think that watching TV means that not only are you sedentary, but you have to watch food advertisement inducing you to eat more. The food that you are being induced to eat may not be good enough for you health.

If you are a couch potato, here are some suggestions:

Tape a piece of paper to the back of your remote control or TV Guide, and every time you watch a show, note how long you sit there and what you eat..

Review the record after a week. This can be a shock.

Don’t have a TV in your bedroom; having a TV in your bedroom greatly increases viewing time and if you tend to eat while viewing, the results are obvious.

Think of a healthy way instead of watching TV that you like. This can be as simply as walking the dog or walking to visit a neighbor regularly.

After a few months you are likely to be surprised about how much more time you seem to have and how much better you feel.

(Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)

The phrase “a couch potato” best describe a person who ___________.

The author believes watching TV _______________ your brain.

Why shouldn’t you put a TV set in your bedroom?______________.

According to the passage, which maybe the healthy ways? ___________.

The term “multitasking” originally referred to a computer's ability to carry out several tasks at one time. For many people, multitasking has become a way of life and even a key to success. In fact, some excellent mental aerobic exercises (大腦訓練) involve engaging the brain in two or more challenging activities at a time. Although checking e-mail while talking on a phone and reading the newspaper may be second nature for some people, many times multitasking can make us less productive, rather than more. And studies show that too much multitasking can lead to increased stress, anxiety and memory loss.

In order to multitask, the brain uses an area known as the prefrontal cortex (前額葉腦皮層). Brain scans of volunteers performing multiple tasks together show that as they shift from task to task, this front part of the brain actually takes a moment of rest between tasks. You may have experienced a prefrontal cortex “moment of rest” yourself if you've ever dialed (撥電話) a phone number and suddenly forgotten who you called when the line is answered. What probably occurred is that between the dialing and the answering, your mind shifted to another thought or task, and then took that “moment” to come back. Research has also shown that for many volunteers, job efficiency (效率) declines while multitasking, as compared to when they perform only one task at a time.

Multitasking is easiest when at least one of the tasks is habitual, or requires little thought. Most people don' t find it difficult to eat and read the newspaper at the same time. However, when two or more attention-requiring tasks are attempted at one time, people sometimes make mistakes.

We often don't remember things as well when we're trying to manage several details at the same time. Without mental focus, we may not pay enough attention to new information coming in, so it never makes it into our memory stores. That is one of the main reasons we forget people's names—even sometimes right after they have introduced themselves. Multitasking can also affect our relationships. If someone checks their e-mail while on the phone with a friend, they may come off as absent-minded or disinterested. It can also cause that person to miss or overlook key information being passed on to them.

1. Why are some mental aerobic exercises designed to engage people in multitasking?

A. To make them more productive.                

B. To reduce their stress and anxiety.

C. To develop their communication Skills.         

D. To help them perform daily tasks more easily.

2. According to Paragraph 2, why may a person suddenly forget who he has called?

A. He may have his prefrontal cortex temporarily damaged.    

B. He is probably interrupted by another task.

C. He is probably not very familiar with the person he has called.    

D. He may need a rest between dialing and speaking.

3. People tend to make mistakes when       .

A. they perform several challenging tasks at a time 

B. new messages are processed one after another    

C. their relationships with others are affected       

D. the tasks require little thought

4. What is the main idea of the passage?

A. Multitasking has become a way of life.

B. Multitasking often leads to efficiency decline.

C. Multitasking exercises need to be improved.

D. Multitasking enables people to remember things better.
